Unless you've been involved with Kamara personally on this injury, it's not really relevant. The club appear to be saying 4-5 months. Forgive me if I take their word over yours, given that they're the ones who are actually managing Kamara's injury.
Which would be a fair assumption if we didn't have the club seemingly telling journos that it's likely to be 4-5 months.
As I said, it's just odd. There's no need to make stuff up now.
